Title: Sealing device for an access lid
Inventor: NISKANEN AULIS
IPC: B63B19/26
Filed: 1983-12-20
Abstract: A sealing device for an access lid (hatch cover) comprises an elastic seal (18) which is inserted into a U-profile. In order to facilitate a sliding movement during the end phase of closing, during which the lid wall slides along the hatch edging, and in order to obtain a sound seal without using a step in the hatch edging, which is pressed into the seal, the seal is formed with a basically V-shaped cross-sectional profile. The vertex angle  alpha  of the bottom area (20) of the seal is relatively large, which means that the contact surface (21) is small as long as the seal is not acted upon by any marked loading. The angle ss determines the top area (19) of the seal, which top area (19) is enclosed by the U-profile, and is noticeably smaller than the projecting angle  alpha . Two passages (23) running in the longitudinal direction are formed in the seal (18), and the top side of the seal contains a wide recess (22) extending in the longitudinal direction. The top corners (24) of the seal are cut off at an angle, and the empty space which is thus formed inside the seal between it and the U-profile (17) permits effective compression of the seal when the lid wall is closed and pressed down, so that complete tightness is ensured, yet the seal ... with a flat surface ... on the hatch edging ...

Patent DE-3425439-A1 (DE)
Title: Conical wood-splitting apparatus
IPC: B27L7/04
Filed: 1984-07-11
Abstract: In forestry, there is great interest in tree trunks which have been felled in order to obtain firewood being split directly after felling and cutting to length, in order in this way to simplify transportation. The subject-matter of the invention is a portable device which is characterised in that a splitting cone which can rotate and has a helical tip (1), transmission (2) and stop (3) whose height can be displaced is constructed such that a firm connection to a motor-driven saw or a similar drive unit can be produced in a simple manner, so that the splitting cone, transmission and drive unit form a unit which can be manipulated with the hands free, the rotation of the piece of wood with the unit being prevented by a stop, which acts in the rotation direction against the piece of wood which is to be split. The drive (4) is effected via the crankshaft or centrifugal clutch of the motor-driven saw. In consequence, a forestry operation is mechanised which previously had to be carried out predominantly by arduous manual work, since conventional wood-splitting machines generally cannot be used in the woods directly after felling and cutting to length. <IMAGE>

Title: Suspension of the steerable drive axle of a cross-country tractor vehicle
Inventor: RATHKE GERD
IPC: B60G9/02
Filed: 1984-09-11
Abstract: A suspension of the steerable drive axle of a cross-country tractor vehicle, especially of an agricultural tractor, is described. The drive axle is supported so that it can oscillate on a longitudinal control arm, which is in turn sprung and capable of swivelling in relation to the vehicle frame. In order to obtain a high degree of sprung comfort and to reduce the loading of the propshaft transmitting the power flux from the drive assembly to the drive axle, the longitudinal control arm, in the area in which the transmission-side joint of the propshaft is located, is pivotably mounted behind the drive axle on a load-bearing component of the vehicle. The lateral guiding of the longitudinal control arm is undertaken by means of a transverse control arm.

Title: Process for producing a masonry structure, and a heat-insulating shaped element for this purpose
Inventor: KISSEL GERNOT
IPC: E04B2/02
Filed: 1984-09-15
Abstract: The production of a masonry structure, which is provided on one side with an insulating layer comprising shaped elements in the form of strips, is to be improved with respect to achieving a continuously smooth heat-insulating layer and with respect to the production of the masonry structure. For this purpose, it is provided that the shaped elements (2, 7), adjoining one another, are used for aligning the masonry-structure joints and, in correspondence with the vertical progression of the masonry-structure courses, are assembled to form the heat-insulating layer and are anchored by the mortar in the mortar joints in the masonry structure (4, 5, 6; 8, 9, 10). The shaped element used is one whose width corresponds to the width of a plurality of masonry blocks (4, 5, 6), including the masonry joints located therebetween, and whose height corresponds at least to the height of the masonry blocks (4, 5, 6) plus the masonry joint. Shoulders (19, 20, 20a, 21, 22, 23) which determine the joint spacing and the position of the masonry blocks (4, 5, 6) are provided at the inner side of the shaped element (2, 7). <IMAGE>

Title: Granulation device with pressure-relieved die plate
Inventor: RUST HARALD DIPL ING
IPC: B29B9/06
Filed: 1984-10-11
Abstract: Devices for granulating thermoplastics possess die plates of large thickness which are intended to prevent deformation of said die plates. The outlet bores of these die plates have high flow resistances which have to be overcome by correspondingly high pressures of the plastication units. A device for granulating thermoplastics is to be improved such that, with the use of die plates of low flow resistance, a deformation of the die plates is prevented. For this purpose, it is proposed to support the die plate in its central region by means of an adjustable plunger.

Title: Rare metal alloy of high tissue tolerance for dental metal ceramics
Inventor: KOERBER KARLHEINZ PROF DR
IPC: A61K6/04
Filed: 1984-12-24
Abstract: Conventional rare metal alloys for fusing to porcelain contain base alloy constituents such as copper, iron, tin and the like to improve the mechanical properties and the adhesion to ceramics. In conventional dental castings, however, electrochemical activities arise due to inhomogeneities and microporosities, and these lead to a continuous release of metal ions of the base alloy constituents. As a consequence, pathological phenomena extending to allergies are observed in the mouth. To avoid these side effects, the alloys according to the invention consist exclusively of gold and metals from the platinum group. By appropriate variation of the proportions, both the solidus temperature and the mechanical data can be adjusted corresponding to the requirements of dental metal ceramics.

Title: Gripper for a manipulating appliance
Inventor: HEIMUELLER HANS JOST
IPC: B25J15/00
Filed: 1985-01-30
Abstract: Grippers of a known type of construction are flexibly anchored to a fastening flange of the manipulating appliance and can thereby compensate for a positional deviation between the gripper and the workpiece to be gripped. According to the invention, the clamping jaws (2) of the gripper are displaceably mounted directly on supporting jaws (3). This results in very low inertia forces with a favourable centre of inertia when compensating for the positional deviations. Tilting moments and pitching oscillations are thereby largely avoided. <IMAGE>

Patent DE-3504347-A1 (DE)
Title: External-rotor motor
Inventor: KRATZ GERHARD
IPC: H02K19/10
Filed: 1985-02-06
Abstract: The object of the invention is to make it possible to use (and, in particular, to operate) the external-rotor motor with an inner stator which has a multi-phase winding and an external rotor, which engages around like a pot and is connected to the motor shaft, up to the medium-power range, the primary factors being simple construction and modular technology. This is achieved in that the motor can be operated with the same stator construction (6, 7, 8, 9) with various external-rotor types, which are replaceable in a modular manner and differ in the manner of their internal design and via which the motor type and the motor behaviour can be defined in an application-specific manner. It is particularly expedient for the replacement of the external-rotor types to be capable of being carried out just via an external replaceable hollow cylinder (3) which differs in the type of the internal design and which is connected, via a supporting disc (2) which does not have to be replaced, to a rotor shaft (1) which does not have to be replaced. A synchronous or asynchronous behaviour of the motor can easily be produced for various application possibilities. <IMAGE>

Title: Device and method for the preheating of parts of an internal combustion engine
Inventor: KAUBEK FRITZ DIPL ING
IPC: F02N19/02
Filed: 1985-02-12
Abstract: Device and method for the preheating of parts of an internal combustion engine by utilising the heat of reaction of a solid reaction medium and a working medium. The heat of reaction is transmitted to the engine parts to be heated by evaporation and subsequent condensation of a certain amount of working medium. For subsequent separation of the reacting agents, heat from the exhaust gas of the internal combustion engine is used. Zeolites are suitable as reaction media and ammonia or water with antifreeze as working media. By means of a special flow control of the working medium vehicle parts which have no influence on the warm-up phase and some of the reaction medium are cooled to less than the ambient temperature. The amount of heat thereby obtained is transformed to a high temperature by the device and transmitted to other engine parts. The required amount of the reacting agents can thereby be reduced.
